Description
Technical field
The present invention relates to the plumbing technical field, relate in particular to constant temperature constant pressure valve core.
Background technique
Progress and growth in the living standard along with science and technology, spool with constant temperature function has been widely used in various bathing water systems such as family, hotel, its characteristics are, the user can adjust coolant-temperature gage according to actual needs voluntarily, after temperature is set, mix effluent temperature constancy, can avoid common spool because of the sometimes hot and sometimes cold problem of water-exit temperature that intake pressure changes and the temperature instability causes, safety is anti-scald.
Effectively the key point of control effluent temperature constancy is the water-exit temperature that sensing is authentic and valid, and the ratio that can regulate cold and hot water inlet delicately.The water-exit temperature that described sensing is authentic and valid is meant that hot and cold water will fully mix, the temperature of sensing mixing water outlet, and this point prior art can solve comparatively perfectly;
In addition, the weighing apparatus pressure of control water inlet also is the key factor that guarantees effluent temperature constancy.Existing constant temperature valve core major part does not provide the weighing apparatus compression functions, promptly cold water, hot water from the spool bottom or side directly enter to mix in the water cavity and mix; And the small part constant temperature valve core that provides the weighing apparatus compression functions is to adopt independently to weigh to press assembly to control, its principle is to press floating of assembly by weighing apparatus, the balance intake pressure, as No. 200620053245.1 utility model patents of China, yet, adopt independent weighing apparatus to press the defective of element to be: complex structure is difficult for assembling.
In addition, existing constant temperature valve core can be for the wider range of regulating, and its upper limiting temperature value is bigger, does not insure temperature controlling, makes like this when misoperation, and accidents such as scald very easily take place because of water-exit temperature is too high,
Summary of the invention
The invention provides a kind of single handle constant temperature constant pressure valve core, purpose is on the basis of constant temperature function, by simple structure, forms tortuous water inlet path, utilizes tortuous water inlet path to realize the function that weighing apparatus is pressed.
Above-mentioned purpose is realized by following technological scheme:
A kind of single handle successive type thermostatic valve core comprises valve pocket, reaches the temperature adjustment component, thermosensitive element, Returnning spring and the regulator that are arranged on the valve pocket inner chamber from top to bottom ordinatedly, and the valve pocket bottom offers cold water intake and hot water intake, and the valve pocket middle part sets out the mouth of a river; It is characterized in that: also comprise the hydroseparator structure and compress Sealing, the hydroseparator structure cooperates with described cold water intake, hot water intake, limit out cold water pathway and hot water passageway, and cold water control mouth, the hot water control mouth that cooperates with described cold water pathway, hot water passageway respectively is provided; Compress Sealing and valve sleeving inner wall and form sealing, and the hydroseparator structure is pressed in the valve pocket; Described regulator cooperates with thermosensitive element and Returnning spring, is subjected to the effect of thermosensitive element and return spring, floats between cold water control mouth and hot water control mouth.
Described temperature adjustment component comprises valve rod, valve rod linking mechanism and limits warm adjusting screw, valve rod top is stretched out by the top of described temperature adjustment valve pocket, the valve rod linking mechanism cooperates with stem lower portion, be subjected to valve rod to drive action up and down reciprocatingly, valve rod is provided with inner bolt hole, and the inner bolt hole inner height is provided with the limit temperature adjusting screw of can be downwards replacing with described valve rod linking mechanism adjustablely.
Among the present invention, temperature regulation, temperature-sensitive and cold and hot water inlet proportional control partly keep structure similar to traditional constant temperature valve core and effect, have guaranteed the constant temperature function; By the hydroseparator structure is set, when it isolates cold and hot water inlet, formed tortuous water inlet path respectively, theoretically, tortuous water inlet path has certain resistance or inhibitory action to water inlet, according to experiment showed, that tortuous water inlet path has tangible effect to the balance intake pressure; The limit temperature adjusting screw that is provided with in the inner bolt hole of valve rod can be replaced with described valve rod linking mechanism downwards, by regulating the height of the warm adjusting screw of limit, the CLV ceiling limit value of temperature adjustment when using can be set.The present invention also has advantage simple in structure, safe and reliable.
